Title: Fender and its manufacture
Inventor: YAMAGUCHI NOBORU
IPC: E02B3/26
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To increase joining strength and prolong the life of a sliding synthetic resin plate by fusing a layer of a specified thickness to the rear face of the sliding synthetic resin plate of a specified thickness, and joining a rubber layer to a rubber fender and a fender having a sliding synthetic resin plate. SOLUTION: In order to manufacture a fender 1, a sliding synthetic resin plate 4 and a rubber layer 3 are fused in advance, and the synthetic resin plate 4 having the rubber layer 3 and a rubber fender 2 are joined by vulcanization. The synthetic resin plate 4 is preferably a polyethylene plate of ultrahigh molecular weight and have a thickness of 10 to 100 mm, more preferably 30 to 50 mm. Use of a thicker plate helps make it longer-lasting. The rubber layer 2 is preferably thin, measuring 1 to 50 mm in thickness. A reduction in thickness allows the rubber layer 3 and the synthetic resin plate 4 to be fused by heating the interface between them. Therefore, joining strength can be increased and the life of the synthetic resin plate 4 can be prolonged.

Title: High frequency and high output hybrid integrated circuit
Inventor: DEGUCHI KAZUHIDE
IPC: H03F3/213
Filed: 1984-12-07
Abstract: PURPOSE:To reduce accessories and to facilitate assembly by incorporating a circuit element which controls output power in a hybrid integrated circuit. CONSTITUTION:A power transistor (TR) 1 for output power control is incorporated in the integrated circuit. When a specific voltage is impressed to the final-stage power terminal 6 of the high-frequency and high-output hybrid integrated circuit and a voltage of about 0.7V is impressed to the power terminal 3 for output power control, the power TR1 turns on. When high-frequency input power is supplied from an input terminal 8 in said state, high-frequency power is passed through matching circuits 9, amplified by high-frequency and high-output TRs 4 and 5, and outputted from an output terminal 7. At this time, when a voltage for output power control is lowered below 0.7V, the power TR1 turns off and the current flowing through the power TR1 and the collector potential of the TR4 are reduced to control the output power of the hybrid integrated circuit.

Title: Write-once information recording medium
Inventor: OGAWA SHUICHIRO
IPC: G11B7/241
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To obtain excellent jitter characteristics for high-density recording by successively forming a crystallization accelerating layer and a recording layer on a transparent substrate and forming the crystallization accelerating layer before the recording layer is deposited. SOLUTION: This optical information recording medium consists of at least a transparent substrate and a recording layer, and a crystallization accelerating layer comprising elements except for group VI elements is formed just under the recording layer.

Title: Controller for magnetic disk device
Inventor: HIBINO YOZO
IPC: G11B21/10
Filed: 1989-10-06
Abstract: PURPOSE:To make a settling time required for leading in a target track short and to control over-shooting from the target track to be small by properly setting a cut-off frequency, a phase margin, a gain margin or the like. CONSTITUTION:A switching controller 8, a seeking controller 9, a settling controller 10, a following controller 11 or the like are included in a device and the digital filter 19 of the settling controller 10 serially connects primary phase- lead filters 17 for low-pass and for high-pass. Due to that, the respective filters 17 can properly select phase-lead. Besides, since the lower bent point of the high-pass filter is situated on the low frequency side of the upper bent point of the low-pass filter, the extent of the superposition can be properly selected. As a result, since the phase margin can be properly selected as a whole and the cut-off frequency, the gain margin and steady-state deviation can be properly selected at the same time, the degree of freedom of design for making a transit characteristic excellent is high. Thus, the settling time required for leading in the target track is made short and the over-shooting from the target track is checked.
